To aZZ whom it may concern:

Be it known that I, OTTo LAUBER, a subject of the German Emperor, and a resident of 133 Margaretenstrasse, Essen-on-theRuhr, Germany, have invented certain new and useful Improvements in Means of Securing Shields to Portable Guns, of which the following is a specification.

The present invention relates to means of securing shields to portable guns, and is particularly adapted for use in portable guns in which a rigid protecting-shield extends over the entire width of the space between the gun-wheels. In such guns it has been proposed to secure the protecting-shield at two places only and rigidly with the wheel-axle. This manner of securing, however, causes the shield to vibrate and become bent by reason of shocks to which it is subjected in transportation, thereby imposing a great strain on the shield and its connections with the axle. It has further been proposed to connect the shield rigidly with the wheel-axle at four places. This manner of securing reduces vibration in the shield, but still permits transverse vibrations of the wheel-axle to be transmitted to the shield and imposes upon the shields axle connections even greater strain than arises from vibrations in the shield itself.

v The object of the present invention is to reduce to a minimum the strain on the shield and its connections with the axle, and the said object is attained by connecting the shield with the wheel-axle at four places and by making at least two of the four connections (at least one connection to each side of the mount) yielding.

. In the accompanying drawings, in which an embodiment of the invention is shown by the way of example, Figure 1 shows a top view of the invention and the parts associated therewith. Fig. 2 is a section on line 2 2, Fig 1, on an enlarged scale. Fig. 3 is a section on line 3 3, Fig. 1, on an enlarged scale.

Projecting rearwardly from the axle A of the mount-body B and near each wheel-hub is a non-rotatable and non-slidable single arm shield-carrier C, to which the rigid shield E, extending over the entire width of the space between the wheels, is rigidly connected through the medium of lugs e, each of which is composed of two angle-plates riveted to the shield. On either side of the mountbody B and adjacent to the cheeks thereof the wheel-axle is further provided with rigidly-attached two-armed shield-carriersD D, Figs. 1 and 3, of which the arms D are yieldingly connected to lugs 6 similar to lugs e, in such a manner that the axle can swing up and down relatively to the lugs e To attain this object, the following arrangement is provided: A bolt F (see Fig. 3) is loosely inserted through a vertical opening in the lug e and a corresponding opening in the arm D, with its head resting on the lug e and a nut f on its opposite end. Between the upper face of the arm D and the lug e is inserted a cushion G of compressed felt or the like and provided with sheet-metal caps g on its upper and lower faces. Between the lower face of the arm D and the nut f is inserted a similar cushion H, provided with caps h. The cushions and their caps are provided with perforations for the insertion of the bolt F. The arm D of the carriers D D is yieldingly connected to an upwardly-inclined brace 6 which is riveted to the shield E. The manner of connecting the arm D with the brace c is similar to that followed in connecting the arm D with the lug 6 with the exception that a pair of dish-springs K are substituted for the cushion H. The felt cushions and the springs K absorb the vertically-directed transverse vibrations of the wheel axle which take place during the travel, and the strain on the shield and on its connections with the axle is therefore reduced to a minimum.

It is a matter of course that it would be within the scope of the invention to provide yielding connections between the shield-carrier C and the lugs e such as that employed between the carriers D D and the lugs e and braces 6 Having thus described the invention, the following is what is claimed as new therein:

1. In a portable gun, the combination with the wheel-axle, of a protecting-shield having both rigid and cushioned connections with the wheel-axle.

2. In a portable gun, the combination with the wheel-axle and the mount, of a protecting-shield having both rigid and cushioned connections with the axle on each side of the mount.

3. In a portable gun, the combination with the Wheel-axle, of a rigid protecting-shield extending over the width of the space between the wheels, between the shield and the axle absorbing v1- bration from the axle.

and cushioned connections and rigidly connected with the shield, twoarmed shield-carriers projecting from the axle on either side of the body of the mount 4. In a portable gun, the combination with having their rear arms in cushioned connecthe wheel-axle, of a protectingshield, rearwardly-projecting arms rigidly connecting the shield to the axle, double arms projecting both forward and rearward from the axle, each having at one end cushioned connections with the shield, and braces having cushioned connection with each of said double arms, and rigid connections with the shield.

5. A portable wheeled gun-mount having a shield extending across the space between the wheels, single-arm shield-carriers project ing rearwardly from the axle near each wheel,

tion with the shield, and upwardly-inclined braces having their lower ends in cushioned connection with the forward arms of said two-armed shield-carriers, and their upper ends in rigid connection with the shield.

The foregoing specification signed at Dilsseldorf this 14th day of July, 1905.
